Typically larger in size, they are available in paper and synthetic materials for use on non-metallic surfaces, plastics or corrugate. Tags that feature inlays that offer a higher level of read performance when placed on or near challenging materials or need to be read at an angle and where longer ranges are required. ![]() Tags that feature RFID inlays designed to provide optimal read ranges in most applications Typically smaller in size, they are available in paper and synthetic materials for use on non-metallic surfaces, plastics or corrugate. What are the types of RFID Tags? General Purpose There are industrial tags available in the market that will withstand temperatures as high as 250º C, which could, for example, stand up to heat sterilization requirements for medical items. These values will vary from manufacturer to manufacturer and will depend on the tag components. Storage temperature typically is between -40º C and 85º C. The typical operating temperature for an RFID inlay (tag) found in most smart labels is between -25º C and 70º C. Passive tags (non-battery) typically have anywhere from 64 bits to 1 kilobyte of nonvolatile memory.Īctive tags, such as those used in military tags, have memories as high as 128 kilobytes. Many active tags utilize battery-backed SRAM. Some are laser programmed at the silicon level. The majority of passive tags use EEPROM memory. The way the tag receives its power determines whether it is passive, semi-passive or active. In order to function, all tags need power to energize the chip and to transmit and receive data. You can categorize RFID tags in different ways by power source, frequency and form factor. Unlike barcodes, in an RFID system, many tags are read simultaneously and data is read from and written to a tag. They contain more information and data capacity as compared to barcodes. Tags identify, categorize and track specific assets. RFID Tags contain electronically-stored information that acts as a label for object identification. Tags also can be read-only (stored data can be read but not changed), read/write (stored data can be altered or rewritten), or a combination, in which some data is permanently stored while other memory is left accessible for later encoding and updates.Ī tag power source can be passive, semi-passive or active, they are designed to function on specific frequencies or frequency ranges and come in many form factors such as labels, wristbands, buttons or embedded into items. RFID tags are either no battery or self-powered by a battery. ![]() Data is stored in the IC and transmitted through the antenna to a reader. RFID tags can come in many forms and sizes. Tags are sometimes called 'transponders', and sometimes are called inlays, although technically an inlay is a tag mounted on a substrate that is ready to be converted into a smart label. RFID tags consist of an integrated circuit (IC) attached to an antenna with typically a small coil of wires plus some protective packaging (like a plastic card) as determined by the application requirements. ![]()
